LASTING-TACK FULLER."

T 0 .'.zz whom it may concern:

Be it known that I, JAMES H. Brenna. a

in Lasting- Tack Pullers, of which;the following is a specification containing a full,

' clear, and exact description, reference being had to the accompanying draw1ngs,form1ng a part hereof.

My invention relates to an improved machine for pulling the lasting tacks. WhlCh temporarily hold the welt shoenpper and insole on the last, and the inventlon consists in the novel construction andcombination of parts hereinafter fully described, and substantially as pointed out in the claim U found at the end of the descriptive portion of this specification,

The object of my present invention 1s to improve upon the machine which is shown and described in my former U. S. Patent I No. 1,004,081, granted to me under date of September 26, 1911, for a lasting-tack puller; whereby the machine will be more 'complete and efficient, aswell as being .mounted upon its own portable base and standard carrying its independent motor,

thereby permittingthe machine to be readily -moved whenever required.

In the drawings,

Fig. 2 is an enlarged detail cross-section of the revoluble head of the tack puller,

Fig.3is a detail side-elevation of one" of I the combination rotary jaw and comb slides,

in Fig. 3, looking at same in the directioninremoved from the head. l i

Fig. 4 is an end view of the slide shown dicated by the arrows H of Fig.3.

Fig. 5 is a top plan-view of the bearing and-cam, in which the revoluble head to be mounted.

I Fig, 6 is a cross-section of the revoluble "head, the section being taken on'th'e line 6-6 of Fig. 7, and a a Fig. 7 is a side-elevation of the revoluble head, detached from the bearing and cam.

My improved tack puller is adapted to operate immediately-in advance of the needle of the inseam sewing machine (not shown), to positively and accurately engage and pull allof the ta'cks, and thus 'leavejthe Specification of Letters Patent. I Patented Sept, 2, 1919, Application filed February 25,: 1918. Serial No. 219,085.

isrnade in sections carrying rotating jaws which move axiallyof the head to clamp the tacks between said fixed circular jaw and saidwrotating sectionalcjaws, and pull said tacks as the entire head rotates, and which sectional jaws finally release and discharge the vpulledtacks; said sections also carrying each a series of curved comb-teeth which engage and pull any tacks which the carelessness of the operator may have caused the 1 said jaws to miss during the operation of the machine. s, u The numeral 1 designates a standard rismg froma suitable base-plate 2 and having .fixedupon its upper end a combined headbearing and cam 3.-

This combined device I shall hereinafter designate the head-bearing of the machine. .Mounted to rotate in the said head-bearing 3 is a horizontal jaw-head 4 having a plain end 5 on which is fixed a suitable puley 6, by means of which power maybeim- -parted to the said head from any desired source, to rotate the latter in the direction 2 indicated b I the arrow in Fig. 2.

Arrangec to slide freely upon the said aw-head 1 are a series of plates 7, which are guided by the Walls of longitudinal grooves 8 formed in the periphery of the head, the said plates being held inposition Sin-the said grooves by contact-with the in .-teri0r of the said head-bearing 3, whose bore their outer surfaces are'curved to fit at the p01I1t. of contact with the said-bore:

The said head-bearing 3 is soifixed upon Y the upper end of the said standardl that (as shown in Figs. 1 and 5) the right-hand end orfedge. of said bearingis the reverse in contour of the left-hand edge of same; that is, there is a high cam-surface 9 anda low camsurface 9. on the right-hand edge, and a low 1 cam-surface 9" on the opposite edge of said bearing directly opposite (and the reverse of the shape of)-thesaid high cam-surfacdQ, 'while there is also a high cam-surface9' directly opposite in a horizontal. planethe said low cam-surface 9 and the upper Q'edges of the cam-surfaces at theri'ght-hahd oular jaw the cam-lug 10 of the particular "series of hooks 'o'r comb teeth 10*, which teeth are located between the 's'aidcam-lug and the left-hand end of the said plates, on which is formed or attached a segmental jaw 11, the outer face of which is provided with radial or other form of corrugations or serrations 12, to clamp the tacks to he pulled between themselves and the adjacent surface of a circular j awor disk 14 which is fixed or forinedupon the end of the said jawhead 4 that is cpjpesite that 'on which the said, wheel or pulley 6 is lined.

The said *c'anr-lugs 1 0 engage the clam-sun faceson cn'e edge of the said head-bearing "3, to move the said sliding plates 7 in one Pdirectioh, and suitable rollers 110 are'mounted on the plates -'to engage the cam-surfaces on the edge thereofwhich is opposite the edge engaged by the saidicam-lugs "and -mov the {plates in an opposite direction. 7

A suitable portable motor, whichis an electric motor 15 in the present illustration 'of my invention, is mounted upon the hori- 'zontal arm of a bracket or platform 16 having a sleeve 17 mounted to slide Vertically'on the standard 1 and adjustably held in position by the set-screw =18.

Fixed upon the armature shaft of the said motor *1'5 is-a common pulley '19 which is en gauged by any common form of flexible belt 20, through which the power of said motor is transmitted to the pulley 6 of the said jawhead 4, whereby the motor and the-tackpulling machine will be combined to form an independent unit, which can be bodily moved from place to place intact.

The'operation is as follows: The'j aw-head 4 is rotated within the said head-bearing :3, carrying the said plates 7 withsaid jaw-head; and during such rotation the said plates are 'reciprocated in such "a manner that the segmental-jaws 11 are correspondingly moved toward and from the said-circular jaw 14, which action-is brought about by the'engagement'of thesaid cam-lugs l Oa'nd the said rollers 10 of the plates with thecam-surfaces upon the opposite edges of the said head-bearing, the'said cam-surfaces 'lbeing so disposed that when one of the said jaws 11 moves into position opposite the lowermost portion of said cirzplate which carriesthat particular j aw 11 -willcome inicdnta'ct with thehigh cam surface "9 atgthe bottom of the said head-bearing :to force this particular jaw 11 toward fioliies of thispa'tent may be obtained for breakingfthe needle by engagement. with a theneedle engages tacks-are removed the work is left in perfect condition to be engaged by the needle, and-=1:

' point.

the lowermost portion of the said circular aw 14, andthis action clamps orengages the head of the lasting tacksfwhich' are"'seated in the last to hold certain parts of the shoe thereon, and which last is held in position immediately beneath the pulling machine, or in such position as that the parts of the shoe are readily engaged by the needle of the inseamer; the said comb-teeth 10* engag-- ing and pulling any tacks which may be missed by the said jaws.

v1-l'1e-taoks, after being pulled, are cla-ni'ped between the corrugated face of the segmental jaws 11 and the eircularjaw 14,;andlupon and between the said comb-teeth, and are held in this position and carried around until the said cam-lugs 10'pass the saidhigh-cam surface 9' of the said head-bearing and the said segmental jaws are released by the sliding movement of the said plates which carry:

sai'dljaws, which releases the tacks pulled by the said jaws, the tacks which have been pulled by the said com'b teeth 1-0' being {discharged as soon as lpul ledi very rapidly-,- and occur immediately preceding the sewing of the inseam between the shoe upper and insole, or between the upper,

insole and welt.

. The'operations very positivelyg-and' quickly H remove'the lasting-tacks, and as all of the tacks are removed there is no danger of tack.

The needle of the inseam "sewing machine feeds the work along, andthe tacks are pulled immediately in front of'the pointwhere the work, and thus as all the sewing operation is readily accomplished around the toe of the last withoutleaving any fullness of the upper at this particular I claim} v A lasting-tad rotary jaw-head having a circularsj aw fixed j thereon, series of plates mounted --to slide longitudinally upon said head and provided with segmental-"jaws which clamp the-tacks5 between themselves and said circular jaw; and comb-teeth car-niedby said platesadjahcent said segmentala -aws and moving there missed by with, to puli thewtacks thatare said jaws In test mony whereof "I v have my *n'ame to this specification in presence, of two 120 subscribing witnesses.
